DRIVING MECHANISM FOR SLICING MACHINES.

. Application filed January 20, 1927, Serial No. 1G2,227,yand in Germany March 1, 1525.

This invention relates to machines for slicing meat and other material, and has forone of its objects the provision of a direct connected drive for the rotary slicing knife of a slicing nnichine.

Other objects will appear from the follow ing description.

The invention is exemplified in the combination and arrangement of parts shown in Fig. 3 is a fragmentary elevation on a.

larger scale showing the direct connected drive gearing.

The numeral 10 designates the base or sup porting frame of a slicing machine having a reciprocating carriage 11 mounted thereon and having a rotary slicing knife 12 carried by a spindle 13 journaled in a bearing 14. The bearing 14 is supported on a pedestal 15 secured to the base 10. A bracket 16 is connected with the pedestal 15 and carries a motor 17. A pinion 18 is connected with the shaft 19 of the motor 17 and meshes with a circular rack 20 mounted directly on the slic ing knife 15. The rack 20 is supported by a circular guide formed of a plurality of arcuale members 21 secured to the knife 12 by screws or rivets 22. Each of the members 21 isnotched at its end so that the adjacent ends form recesses -iiwhich receive inwardly projvcting lugs 24; carried on the inner face of the rack 20. Springs 25 are interposed between the lugs 21 and the ends of the arcuate guides 21 so that the rack 20 is yieldingly held against rotary movement relative to the knife 12. The recesses 23 are closed by a circular plate 26 which overlaps the inner edge of the rack 20 and retains the rack in place on the guides 21. It will be seen that the pinion 18 and rack 20 provide a direct drive from the motor to the slicing knife 12 but permit a limited yielding relative movement between the motor and knife.

The mechanism for reciprocating the table 11 is driven from the shaft 13 by means of a sprocket chain 27 passing over a sprocket secured to the spindle 12 and connected with the mechanism for f reciprocating the table 11 in a well-known manner. The yielding connection between the motorlandknife gives the knife a certain amount of yielding movement relative to. the driving mechanism, which is important, especially in caseswhere the knife may strike a hard substance in the material being sliced. Another advantageof the yielding connection is to compensate for change in the load upon the driving mechanism when the direction of rotation of the reciprocating table is reversed.

I claim i 1. The combination with a slicing machine having a rotary slicing knife, of a motor-for driving said knife, a reciprocating table, means for driving said table from said knife, and a'yielding driving connection between said motor and knife. j y

2. The combination with a slicing machine having a rotary slicing knife, of a circular rack connected with'said knife, yielding driving connection between said rack and knife and a motor for driving'said rack.

3. The combination witha slicing machine having a rotary slicingknife, of a circular rack mounted on said knife and having limited rotary movement relative to said knife, yielding means for transmitting force from said rack to said knife, and a motor for driving said rack. l M

txIn combination, aslicing machine having a rotary slicing knife, a circular guide secured to said knife concentric therewith, a circular rack slidably mounted on said guide, resilient means for transmitting force from said rack to said knife, and a'motor for driving said rack.

5. In combination, a slicing machine having a rotary slicing knife, a reciprocating table, driving connection between said knife and table. a circular rack mounted on said knife, resilient means for transmitting force from said rack to said knife, and a motor for drivingsaid rack.

6. In combination, a rotary slicing knife, a sectional circular guide secured to one face of said knife, a rack slidably mounted on said guide concentric with said knife, and yielding means for holding said rack and knife against relative rotary movement.

7. The combination witha slicing knife, of a sectional circular guidejsecured to one face of said knife, said guide having a recess in the outer face thereof, a circular rack slidahly mounted on said guide and having a lug extending into said recess, and a spring interposed between said lug and the end wall of said recess for yieldingly resisting relative rotary movement of said rack and knife.

8. The combination with a rotary slicing knife, of a sectional circular guide secured to one face of said slicing knife said guide 1 aring a recess in the outer face thereof, a circular rack slidahly mounted on said guide and having a lug extending into said recess, springs interposed between said lug and the walls of said recess at opposite sides of said lug for yielding-1y transmitting rotary 1novement from said rack to said slicing knife, and a circular plate disposed against said guide and closing said recess, said plate having a portion thereof overlapping said rack to retain said rack in place on said guide.

9. A slicing machine comprising a reciprocating table, arotary slicing knife, driving connection between said table and knife a circular guide secured to the face of said knife opposite said. reciprocating table, a circular rack slidahly mounted on said guide, si irings for transmitting rotary movement from said rack to said knife, and a motor having a driving pinion meshing with said rack.

In testimony whereof I have signed my name to this specification on this thirtieth day of December A. D. 1926.
